Lifehacker’s article on an NPR report on shampooing stunned me. I saw this line: “National Public Radio’s story, available in text and audio, details the history of the social ideal of washing one’s hair every day” and boggled — daily shampooing is a social ideal? Why wasn’t I told? When did that happen?

I’ve never (nor needed to) washed my hair every day. I had no idea I was transgressing an ideal. Personally, I have no objection to a deliberate transgression of social ideals (which are seldom ideal), but I at least like to know when I’m doing it.
